Subject: swiotlb-xen: pass dev_addr to swiotlb_tbl_unmap_single
From: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>
commit 2c3fc8d26dd09b9d7069687eead849ee81c78e46 upstream.
Need to pass the pointer within the swiotlb internal buffer to the
swiotlb library, that in the case of xen_unmap_single is dev_addr, not
paddr.
